AIM: To investigate the effects of ?-mercaptoethanol (?-ME) and all-trans rentinal acid (RA) on glial fibrillary acidic protein (GFAP) expression in mesenchymal cells derived from mouse fetal liver in vitro. METHODS: Cells suspension from 14.5-days-old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20% FCS and mesenchymal cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ?-ME and RA. The characteristics of treated cells were assayed by immunocytochemistry staining at 5 hours and 5 days after induction. ?-actin as an internal control, GFAP gene expression of mesenchyal cells was detected with semi-quantitative RT-PCR. RESULTS: After being inducted by ?-ME and RA, 80% approximately of the cells exhibited typical neural morphology and about 85% expressed GFAP phenotype. Semi-quantitative RT-PCR showed that mRNA expression of GFAP increased in treated cells versus untreated cells (P

Objective:To investigate potency of mouse fetal liver mesenchymal cells differentiating into neural cells in vitro .Methods: Sterile cells from 14.5 day old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20%FCS and adherent cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ? mercaptoethanol (? ME) and all trans retinoic acid (ATRA). The characteristics of treated cells were assayed by immunocytochemistry staining and semi quantitative RT PCR method on 5 h and 5 d after induction. Results: After induction by ? ME and ATRA, approximately 80% of the cells exhibited typical neuronal morphology;most cells expressed neuronal phenotype such as neuron specific nuclear protein(NeuN), neuron specific tubulin Ⅲ(TuJ 1), neurofilament M(NF M),and neuron specific enolase(NSE).However, microtubule associated protein tau(Tau 1)and microtubule associated protein 2 (MAP 2) as indicators of mature neuronal phenotype were undetectable. Semi quantitative RT PCR showed increased mRNA expression of brain factor 1(BF 1), brain 3(Brn 3), and neurofilament L(NF L) in treated cells versus untreated cells ( P

Objective To analyse correlated risk factors of evolving cerebral infarction(ECI).Methods The follow data was recorded in the acute cerebral infarction (ACI)cases when they were admitted :sex,age,systolic blood pressure(SBP),diastolic blood pressure(DBP),history of disease (diabetes mellitus,hypertension,hyperlipidaemia,cerebral infarction,hyperuricemia or smoking).The following examinations or determinations were done,including:white blood cell count (WBC),platelet count (PLT),blood gluconate(GLU),PT-INR,fibrinogen(FG),TT-INR,APTT-INR,C-reactive protein(CRP),D-dimer(D-D),products of fibrin degradation(FDP),anti-thrombin Ⅲ(ATⅢ),apolipoprotein A(apoA),apolipoprotein B(apoB),blood urea nitrogen(BUN),creatinine(CR),triglyceride (TG),high density lipoprotein (HDL),low density lipoprotein (LDL),very low density lipoprotein (VLDL),GOT,lactate dehydrogenase(LDH),creatine phosphokinase (CPK),MB isoforms of creatine phosphokinase (CPK-MB),? hydroxybutyrate dehydrogenase (?-HBDH),troponin I(TnI),cerebral CT or MRI and carotid ultrasonography.The patients were divided into two groups,ECI and completed cerebral infarction (CCI),according whether neurons function scale deteriorated.When cases of both groups exceeded 50,we took statistic test by SPSS10.0 statistic software.Results 8 of the above 46 markers had significant defference between the two groups,including CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH and DBP.ECI was more common in patients who had lower DBP or higher CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH when they were admitted.Conclusion The increase of CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH or decrease of DBP when patients are admitted can be predictive markers of ECI.

Objective To evaluated the improving effect of training method of point-line-plane on development quotient in premature infants with brain injury.Methods 174 cases of premature children with brain injury were randomly divided into study group (89 cases) and control group (85 cases).Control group given Bobath and Vojta traditional rehabilitation training,and the study group was given training method of point-line-plane.Patients in both groups were evaluated synthetically based on The Evaluation Chart on Neu-robehavioral Development of Children Aged 0-6 Years,developed by Capital Institute of Pediatrics,prior to the treatment,and after the first,the second,and the third course of the training programs,respectively.Re-sults The score of developmental quotient ( DQ) between study group and control group was no significantly different(P>0.05).Compared with before treatment, the scores of DQ was significantly increased after the first, the second and the third course of training treatment in study group and control group((82.71±12.28) vs (81.17±9.63), t=0.859, P>0.05;(89.65±10.02) vs (87.02±7.39), t=1.747, P>0.05). Compared with the control group, the scores of DQ in study group was no significant difference after the first and the second course of treatment,but there was significantiy different after the third course treatment((95.26±8.87) vs (91.31±7.63), t=2.945, P=0.004).Conclusion The training method of point-line-plane can improve the clinical efficacy of premature infants with brain injury at the early phase, which is worth widely applying in clinical practice.

Objective To observe the effects of citalopram and physical therapy on poststroke depression(PSD).Methods72 patients with PSD were randomly divided into medicine group(n=36)and control group(n=36).The patients in the control group were treated only with physical therapy and the patients in the medicine group were treated with Citalopram and physical therapy.All patients were assessed with Zung Self-Rating Depression Scale(ZSDS)and Modified Barthel index(MBI)before and after treatment.ResultsAfter treatment,the Zung score in both groups decreased significantly(P<0.01).Meanwhile,the medicine group showed significantly less depression than the control group(P<0.05).The score of MBI was also significantly increased after treatment(P<0.01)in both group,but there was no significant difference between two groups(P>0.05).ConclusionCitalopram combined with physical therapy is effective on PSD.

Objective To explore the value of transthoracic echocardiography in diagnosis of univentricle and analyze the sonogram typing. Methods The results of 66 patients with univentricle were reviewed retrospectively,and analayzed their typing connected with the reports in the literature. Results There were 3 ultrasonic types in 66 cases:①Type A(single left ventricle) 19 cases,single ventricle with left ventricular shape,residual cavity in front of it. ②Type B(single right ventricle) 38 cases, single ventricle with right ventricular form,and residual cavity in the rear.③Type C (solitary single-ventricle) 9 cases,there was only one ventricle. Thirty-one of them were treated surgically, 5 cases without operation had MRI or cardiac catheterization examination and the remaining 26 patients were only observed by echocardiography,the positive rate of diagnosis in type was 100%, the results were compared with cardiac catheterization or MRI examination and the operation: 1 cases of mixed type total anomalous pulmonary venous connection was misdiagnosed as heart-type total anomalous pulmonary venous drainage. But 1 case of descending aorta limitations narrow complicated patent ductus arteriosus(PDA), PDA was missed. The rest were completely correct diagnosis. Conclusions The transthoracic echocardiography can be used to evaluate types and all containing malformations of univentricle,and offers reliable information for operation.

Objective To investigate the effects of remote ischemic postconditioning (RIPoC) on global cerebral ischemia-reperfusion (I/R) injury in rats.Methods One hundred and twenty-eight male adult SD rats weighing 200-250 g were randomly divided into 4 groups ( n =32 each):sham operation group (group S),group I/R,group I/R + RIPoC and remote I/R group (group RI/R ).Global cerebral I/R was induced by four-vessel occlusion.Group I/R + RIPoC received 3 cycles of 15 min reperfusion followed by 15 min ischemia in bilateral femoral arteries at the beginning of cerebral reperfusion.The rats were sacrificed at 24 and 48 h of cerebral reperfusion,and brains were removed for determination of neuronal apoptosis (by TUNEL method) in hippocampal CA1 region and the parietal cortex,Bcl-2 and Bax expression (by Western blot) in hippocampal CA1 region.The superoxide dismutase (SOD) and catalase (CAT) activity and malondialdehyde (MDA) content in hippocampal CA1 region and the parietal cortex were also measured at 48 h of cerebral reperfusion.Morris water maze task was used to test the learning and memory function at 4 d of cerebral reperfusion,and the rats were sacrificed at 7 d of cerebral reperfusion,and brains were removed for determination of neuronal density in hippocampal CAl region and the parietal cortex.Results Cerebral I/R significantly increased the number of apoptotic neurons and MDA content,upregulated Bcl-2 and Bax expression,decreased neuronal density,SOD and CAT activity and learning and memory function in group I/R as compared with group S.RIPoC significantly attenuated these cerebral I/R-induced changes.Conclusion RIPoC could protect brain against global cerebral I/R-induced injury,and the mechanism may be related to inhibiting lipid peroxidation,regulating the balance between Bcl-2 and Bax and inhibiting apoptosis.

BACKGROUND: Changes in extracellular of chondrocyte can reflect influence of external force on temporomandibular joint and adaptability of body to external force. OBJECTIVE: To study the effect of cyclic tensile stress on main extracellular matrix of condylar chondrocyte.METHODS: The cyclic tensile stress was exposed to the third passage condylar chondrocyte for 0, 1, 6, 12 and 24 hours, respectively, using a Flexcell Strain Unit-5000T system (10% surface elongation, 6 cycles/min). After mechanical loading, total RNA was extracted from the cells harvested from Six-well BioFlex flexible cell Petri Dish, reverse transcribed, and reverse trabscription-PCR was performed to quantify mRNA levels for type Ⅱ collagen and aggrecan.RESULTS AND CONCLUSION: Compared with the control group (0 hour group), both type Ⅱ collagen and aggrecan mRNA expression was significantly increased after loading for 6 hours (P < 0.05), but began to decrease since 12 hours, and significantly decreased at 24 hours (P < 0.05). Results showed that cyclical tensile stress stimuli can affect the synthesis of main extracellular matrix of condylar cartilage, i.e. the synthesis was gradually enhanced with prolonged stimulation duration, but significantly inhibited in response to further stress stimuli.
